I enjoy the 1997 versions the best though they are far from perfect.
So many enhanced shots, sounds and scenes (love the new look of cloud city, victory celebration and approach to Yavin sequence). We also get to keep things like the 20th Century intro, Sebastian’s ghost, Vader’s silence at the end of the death star scene and Fett’s original voice whereas the 2011 versions took those away.
I can deal with the small bit of excess creatures in Mos Eisley if it means getting those extra things I like.
